Firstly, great watch. Thanks for the post @Big Rat
I see what he is saying about too much power. On the road, in anything other than dry conditions, you can't really use the IS-F's 400 ish BHP. If it was 4wd it would be different.
As for his complaints about the the controls, they really are nowhere near as bad as he made out. I do however agree on the sat nav. The newer systems are better than the IS-F's, but still not intuitive at all!
Finally, I wonder how much help Harris has just given the second hand GS-F market?
